Collagen is a large structural protein; collagen peptides are short fragments of it. Research peptides are a different category: specific sequences studied as laboratory reference compounds for research use only.
Three different things
| Collagen | Collagen peptides | Research peptides | |
|---|---|---|---|
| What it is | A structural protein | Fragments of collagen | Specific study sequences |
| Typical context | The body / food | Consumer supplements | Laboratory research |
| Status | n/a | Consumer product | Research use only |
Why the confusion
The word peptide appears in both "collagen peptides" and "research peptides," which is where the mix-up starts. But collagen peptides are broken-down fragments of a food protein sold as a consumer supplement, while research peptides are defined sequences studied in the lab.
Browse research-grade peptides
Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
The key distinction
Research peptides are labeled research use only and ship with a certificate of analysis. Collagen peptides in a supplement are a different kind of product entirely, intended as food. Keeping the two straight matters.
Key takeaways
- Collagen is a large structural protein.
- Collagen peptides are fragments of it, sold as consumer supplements.
- Research peptides are defined sequences studied in the lab.
- Only research peptides are labeled research use only.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
